    Hey Fp!

    When you multiplied X(s) with G(s), you appear to have multiplied x(t) instead with G(s).
    Do you know how to find X(s) from x(t)?

    HEy ILS :)

    Hmm, I did not realize there is a X(s). What exactly is it in words?

    X(s) is the so called Laplace Transform of x(t).
    Typically you use a table with Laplace transforms and look it up.

    For instance, the Laplace transform of x(t)=2 is X(s)=2/s.

    Oh my, I wondered if I stepped out of the bounderies of my class material. I'll go ask my classmate and check, because I don't remember having learnt about it.

    Turns out it is indeed beyond the scope of our material. I went ahead of myself! Thanks anyway :)
